How do I stop emotionally abusing my girlfriend?

i love my girlfriend to death. we've been dating for 5 months now. im 13, turning 14 next month and shes 14 but shes a grade above me. i have a serious problem, i think i might be emontionally abusing her. when i get mad and when we fight, i go over the top and i start manipulating her into thinking shes done extremely wrong when she really hasnt and when its really my fault. i keep making her miserable by doing this and she just keeps giving in and begging for forgiveness. ive even hinted that i know what im doing is wrong, then i completely admitted it to her. it didnt help. i know what im doing is wrong and i want to stop but i just cant, actually i even dont know how to stop. i have a counselor and ive talked about it with her before, but she really hasnt helped. she's helped me with my anger and stress, but not with emotional abuse. i feel like god and the devil are playing tug-a-war with me. half of me knows what im doing is completely wrong, and the other half just feeds off of it. i even know why im doing this: cause i dont get enough attention from my gf and i get it more by making her miserable. i just want to stop. thats all im asking. how do i stop myself from doing this?
